This invention relates to door bumpers or cushioning contrivances which may be located to contact with the knob of a door to take up the possible blow to the wall plastering when the door is more or less violently opened, or it may be attached to a chair or other piece of furniture usually backed against the wall to prevent marring either the chair back or the wall surface.

The object of this invention is the production of a bumper for the purposes stated, which is of simple construction, easily placed in position, and which is very durable and cannot be broken or displaced or rendered inoperative by ordinary use.

The invention also has for its object the special construction and combination of parts illustrated in the accompanying drawing forming a portion of this application.

Fig. I of the drawing shows this invention attached to a lath and plaster wall, shown in section, and in position to meet the knob of an opening door. All parts are shown assembled.

Fig. II shows the back of a chair with this invention in place thereon.

Fig. III is an outer exterior view of the cushion holder.

Fig. IV is a vertical sectional view of the holder taken on line IVIV of Fig. III.

Fig. V is a bottom or base view of the cushion.

Fig. VI is a sectional view of the cushion and base thereof taken along the vertical line VI-VI of Fig. V.

Fig. VII is a vertical sectional view of a portion of a wall of expanded metal and plastering with this invention applied thereto.

Fig. VIII is an exterior or front view of a modified form of the cushion holder of this invention.

Fig. IX represents a base or back view of a modified form of the cushion base of this invention.

Fig. X is a cross sectional view along the line XX of Fig. IX.

Throughout the drawing and description the same number is used to refer to the same part.

In Fig. I the door I hasthe knob 2, and the wall of plaster 3 and lathing 4 is protected by the cushion hemisphere 5 seated in a holder 6 secured to the wall lath by screw 1.

In Fig. II the cushion 5 in holder 6 is applied to the back of a chair 8. Any other piece of furniture may be thus provided.

In Figs. III and IV the cushion holder is best illustrated. It may have on one side or edge a short projecting lug 9, a central bolt hole Ill, and integrally formed raised tongues H. If now the cushion 5 be pushed into the recessed face of the holder over the lug 9, the tongues will be forced into the cushion 5 just over the circular edge of the metal base I2 of the cushion, shown in Figs. V and VI. The cushion is thus secured in the holder 6. The recessed or depressed face of the holder 6 is illustrated in Fig. IV, and the tongues I l are also shown raised over the depressed face.

Upon the wall of plastering IS on expanded metal it as set out in Fig. VII, either the cushion 5 or a modified cushion i5 may be placedin the modifiedholder illustrated. The cushion l5 has two integral extensions of its bottom or back, l6 and H, as shown in Figs. IX and X, and when the cushion is placed in the modified holder 18, the extensions 56 and IT are forced through the openings i9 and 26 in the modified holder l8, as illustrated in Fig, VIII. The expansion of the integral extensions i5 and ii serve to secure the 1 cushion hemisphere E5 in the holder I8. It will be understood that the holder i8 illustrated in Figs. VIII and IX has the dished or cup form as shown in Fig. IV for the holder 6.

As best shown in Fig. VII, the securing means comprise a threaded bolt 22, which is passed through the holder I8 and through the wall. The

bolt has a nut 23 on the inner surface of the wall, and the nut is provided with resilient extensions Zt. When the cushion holder is drawn to the wall the nut 23 with its resilient extensions acts to clamp the holder always firmly to the wall surface, so that no displacement results in the It is not intended to limit this invention to the precise form of holder illustrated in the drawing, as those specific shapes may be readily and variously changed. The cushioning member described herein may be of rubber, or of any sufiiciently resilient material.

The operation of this invention is of the same nature as other like devices for kindred purposes. The cushion is arranged in the path of the door knob, or of the door itself, and may be of any size or degree of elasticity;

Having now described this invention and its use I claim:

A detachable door bumper comprising a re-' silient cushion constructed with a flat portion and having a metal plate firmly attached to said portion and constituting the base of the cushion, a dished metal holder having a central screwhole,

, a screw adapted to be passed through said holder into a wall to support said bumper, said holder having a depressed external surface portion constructed to receive said base plate and provided operation. Holder i8 has the central bolt hole
